We conducted an experiment using a vibration system using which a totally deafblind
participant, communicating through an interpreter, could directly receive back-channel feedback from a conversational partner. Statistical analysis of the interaction structure showed that the back-channel vibration increased the participant’s turn-taking ability and
interactivity during the communication. Moreover, from a qualitative analysis of the video data, we found that the experience of receiving back-channel feedback caused a change in his haptic behavior with respect to that during normal communication. Our results indicate that the low mental workload and learnability of this vibration system allows deafblind persons to improve
their communication. In parallel with the experiment using a vibrator, we conducted a
questionnaire survey among the interpreters, questioning them on their interpretation
behavior.
